Sir Dan is Arguable so that doesnt count.
Toro is in because hes a mascot not because of anything having to do with ps1
Heihachi is in for another fighting rep and has a lot of games on other systems and is considered biggest to some people on other consoles
besides this reason of Croc being in I still have 5 other great reasons and this reason is also great so i have 6 great reasons
Sir Dan is Arguable because MediEvil 2 was somewhat popular, but MediEvil 1 was much more so. Also many reviews point out that MediEvil 2 was essentially whatever couldn't fit into the first game.
Toro is a mascot BECAUSE of his PS1 game
Heihachi is one of the most iconic characters from a series that was HUGE on PS1.
I should mention that almost everybody I know had never heard of Croc until recently, including many hardcore Sony fans who, upon hearing who he was, said "Oh, that crappy Crocodile game?"
We might as well advocate Frogger if we want PS1 characters!
2. Would attract MS fans
3. Would attract FPS fans
4. Would allow Microsoft and Sony to make money.
5. He could have a good moveset
6. His games sell a lot
I can do this for pretty much anybody, so saying that 6 reasons validates a slot for a character means nothing.
